Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

typescript-migrate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

What it actually says

TypeScript Migration Assistant

Migrate $ARGUMENTS from JavaScript to TypeScript with proper typing and modern practices.

Task

I'll help you migrate JavaScript code to TypeScript by:

  1. Converting JavaScript files to TypeScript (.js/.jsx to .ts/.tsx)
  2. Adding appropriate type definitions and interfaces
  3. Configuring TypeScript settings for your project
  4. Resolving type errors and compatibility issues
  5. Implementing modern TypeScript patterns and features
  6. Ensuring backward compatibility with existing code

Process

I'll follow these steps:

  1. Examine your project structure and dependencies
  2. Analyze the JavaScript code to understand its functionality
  3. Create or update tsconfig.json with appropriate settings
  4. Convert files to TypeScript with proper type annotations
  5. Add necessary type definitions for libraries
  6. Fix type errors and implement type safety
  7. Refactor code to leverage TypeScript features

TypeScript Features I Can Implement

  • Interfaces and type aliases for complex data structures
  • Generics for reusable, type-safe components and functions
  • Union and intersection types for flexible typing
  • Enums for related constants
  • Utility types (Partial, Pick, Omit, etc.)
  • Type guards and type narrowing
  • Mapped and conditional types
  • Function overloading
  • Readonly properties and immutability
  • Module augmentation for extending third-party types

Migration Strategies

I can apply different migration approaches based on your needs:

  • Gradual migration with allowJs and incremental adoption
  • File-by-file conversion while maintaining functionality
  • Comprehensive migration with full type safety
  • Hybrid approach with .d.ts files for complex modules
  • Integration with existing type definitions (@types packages)

I'll adapt to your project's specific requirements and ensure a smooth transition to TypeScript while maintaining existing functionality.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
